"A Growing Middle Class Envisages an end to privileges" . Explain this sentence breifly.

The eighteenth century witnessed the emergence of social groups, termed the middle class, who earned their wealth through an expanding overseas trade and from the manufacture of goods such as woollen and silk textiles that were either exported or bought by the richer members of society. The third estate included professions such as lawyers or administrative officials. All of these were educated and believed that no group in society should be privileged by birth. Rather, a person’s social position must depend on his merit. These ideas envisaging a society based on freedom and equal laws and opportunities for all, were put forward by philosophers such as John Locke and Jean Jacques Rousseau. In his Two Treatises of Government, Locke sought to refute the doctrine of the divine and absolute right of the monarch. Rousseau carried the idea forward, proposing a form of government based on a social contract between people and their representatives. In The Spirit of the Laws, Montesquieu proposed a division of power within the government between the legislative, the executive and the judiciary. This model of government was put into force in the USA, after the thirteen colonies declared their independence from Britain. The American constitution and its guarantee of individual rights was an important example for political thinkers in France. The ideas of these philosophers were discussed intensively in salons and coffee-houses and spread among people through books and newspapers. These were frequently read aloud in groups for the benefit of those who could not read and write. The news that Louis XVI planned to impose further taxes to be able to meet the expenses of the state generated anger and protest against the system of privileges. Hence, the growing middle class  spearheaded the French revolution which ended in the abolition of monarchy.
